Climate‐Mediated Hybridisation and the Future of Andean Forests

Journal of Biogeography, EarlyView.
ABSTRACT The tropical Andes face unprecedented warming and shifting precipitation patterns due to climate change and land‐use alteration, challenging the future of Andean forests. During the Quaternary, many Andean trees responded to climate change through upslope migrations but, while there is evidence of such ongoing migrations in many species, they ...

What Are the Phylogenetic Limits to Pollinator Diversity?

Journal of Applied Entomology, EarlyView.
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

An integrative framework reveals widespread gene flow during the early radiation of oaks and relatives in Quercoideae (Fagaceae)

Journal of Integrative Plant Biology, EarlyView.
Multiple lines of evidence from phylogenomics, paleontology, biogeography, and ecology support the occurrence of widespread ancient reticulations between major lineages of Quercus and relatives in Quercoideae (Fagaceae) during the Early to Middle Eocene in North America and Eurasia.
